SUSPENSION DEVl CE PARTlCULARLY ADAPTED FQR CpRTAmIsQ To all whom it may concern.-

l 3e it known that I, Tnonas LUDWIG, a citizen of the German Empire, and a resident of 71 VVertherstrasse, Barmen, Germany,

have invented certain new and useful 1mprovements Relating to Suspension Devices Particularly Adapted for Curtains, of which the following is a specification.

This invention relates to a curtain pole which is made hollow and incloses balls from which the curtain or similar article is suspended by means of rin s. These rings are so guided within the po e that an unseating of the rings is prevented and a free movement of the curtain is insured.

In the accompanying drawing z-Figure ,1 is a plan view of the device as applied to ourtain rods; the path for the balls is shown partly in section. Fig. 2 illustrates a construction of a supporting rod adjustable in length, in elevation. Fig. 3 is a corresponding plan view, and Fig. 4 is a cross-section on the line AA of Fig. 2.

The tube a, which is formed from a strip of metal of appropriate width and thickness, presents a longitudinal slot 12 on its under The balls 0 run with a certain amount as are largely employed in known forms of ball bearings. The rings (Z are placed over the balls 0, likewise with some amount of play; they extend outside the tube through the slot 1). In order to revent the rings from slipping off the bal s c laterally and thereby becoming wedged in the tube a, and also to provide space for their free longitudinal displacement, the tube ais provided on its upper side and diametrically opposite slot 1), with an indented hollow bead e. This hollow bead e likewise serves as a strengthening rib, preventing the sagging and deformation which would otherwise be liable tooccur in the case/oi rods of considerable length having to support any appreciable load, as such rods are generally made from relatively thin sheet metal The curtain holders f are suspended in the outwardly projecting portion of the rings (1, and carry the curtains or the like by means of a fixing device consisting of a ring 9 and a head hiitting into the same. The hem of the curtain or blind i is placed between the ring 9 and the head 71., and clipped between the two by d(- .pressing the slide /r. The blind 'Lma'y then readily be drawn to and fro either by hand or by means of a cord in the known Specification of Letters Patent.

manner. The balls 0, with the rings (1 arranged over them, are introduced from the open side of the tube a, which may then be closed' in any convenient manner. If in place of blinds or curtains t other articles are to be displaceably suspended on the novel supporting rod, the curtain holders fin the rings d may be replaced by hooks, from which the articles in question may be suspended.

The constructional form represented in Figs. 2 to 4 illustrates the mannerin which a supporting rod in accordance with the invention may be adjusted to any desired length, as is re uired owing to the variation in the, width or the doors or windows at which the supporting rods may have to be arranged. As, however, this amount only varies within small limits, it is suflicient to supply support ing rods the length of which may be varied somewhat above or below' a given normal size. The supporting rod here represented, which in the main corresponds to that already described, is in this case com used of two parts a and a, the ends of wiich overlap. On each of these ends, the sliding parts Z and Z are fixed respectively, and slide freely on the other member of the tube, by which means both the tube members a and a receive a parallel guidance, and are likewise rendered capable of supporting bending strains. Now, as the slot 2 on the under side of the tubes a and a is also carried through the sliding parts Z and Z, the rings (Z are able to pass over the places where the two tubes meet, which is not the case wherev the rings are passed over supporting rodsin the known manner. Bymeans of this device, which is intended mainly for curtains in two parts, it is therefore possible to draw the curtains close together, or even to cause them to overlap. The outer ends of the tubular members a and a. are pressed so as to form lugs m b y means of which the support-- ing rod may be fixed in position.

Claims:
